I'll try to find a windows convertor.
Any more suggestions ?
What do you guys use to convert ?

.. would be nice to point a tool like above at a folder and say "off you go" and it converts the lot!
Convert from 16-bit to 8-bit by discarding the least significant 8 bits (i.e. just take the most significant byte).
Then reduce to simple fractions like 3/4, 2/3, 1/2, 1/3 or 1/4 frequency by skipping bytes or taking averages of each few bytes.
Its worth noting that 1/3 of 44.1KHz (CD playback frequency) is a little under 15KHz which is the frequency you get if you synchronise sample playback with scanline redraw (At 50Hz/PAL) which is useful if you want to play samples alonside rasters/plasmas/fullscreens etc.
You may want to convert to unsigned format as this is best for playback via the ST's YM2149 sound chip. I believe this is just a case of adding 128 to each signed byte.
